John Travolta had a six-year fling with his personal pilot, in a completely open secret known to people close to the “Urban Cowboy” actor, according to published reports.

The National Enquirer quoted the actor’s former personal secretary and a boyfriend of the pilot to back up the steamy, bombshell claims.

“I did everything for him, including taking care of his personal and professional schedules. Of course I knew he was gay. It never bothered me,” one-time secretary Joan Edwards told the supermarket tab.

Pilot Doug Gotterba, who now runs a charter plane service in Camarillo, Calif., would only confirm that he worked for Travolta for six years in the 1980s.

“That’s how I met Doug. We both worked for John at the same time. Doug is a wonderful guy and we are still good friends. He told me that John was gay and they had a sexual relationship,” according to Edwards.

Gotterba’s one-time boyfriend Robert Britz said the pilot was very open about his years-long gay relationship with Travolta.

“Doug told me right at the beginning of our relationship that he’d had a homosexual relationship with John Travolta in the 1980s,” Britz said.

“Doug said John was constantly grabbing at his genital area, but he put up with John’s sexual advances because working for him was ‘lucrative.’ ”

Travolta’s personal flyboy eventually turned away from the actor, grossed out by his weight and B.O., according to Britz.

“Doug said he hated sleeping with John because his body was very hairy, and he didn’t like the way John smelled,” Britz said.

“John became very heavy between movies. Doug recalled him ‘huge’ and said it turned him off.

Travolta’s is fighting lawsuits by two male massage therapists, who claim the actor made unwanted sexual advances.
